Summary Breakout board for ESP8266.
This is a breakout board for ESP8266 (SP-03) . ESP8266 is a standalone wifi module with an in built microcontroller which has brough a revolution in IOT.This board gives you access to all of it's power and GPIO pins very easily.
Pin configuration:
Pin |
Name |
Alternate Functions |
Notes |
1 |
GND |
(Pin 1 is in the corner close to the xtal and away from antenna) |
|
2 |
NC |
||
3 |
UTXD |
SPICS1, GPIO1, CLK_RTC |
Typically used as serial uart0 TX |
4 |
URXD |
I2SO_DATA, GPIO3, CLK_XTAL |
Typically used as serial uart0 RX |
5 |
GPIO16 |
XPD_DCDC, RTC_GPIO0, EXT_WAKEUP, DEEPSLEEP |
Connected to XPD_DCDC ESP pin, can also be connected to ESP EXT_RSTB (reset) pin by closing jumper near pin 8; Reset pin is active low and has an internal weak pull-up; Connecting jumper is required to wake-up ESP from deep-sleep: RTC produces pulse on XPD_DCDC pin that needs to be fed into EXT_RSTB pin |
6 |
CH_PD |
Power-down: low input powers down chip, high powers up; tie high for normal operation or module will not function |
|
7 |
ANT |
Wifi Antenna, do not connect |
|
8 |
VCC |
3.3V input (pin 8 is between antenna and ESP chip) |
|
9 |
GPIO14 |
MTMS, I2SI_WS, SP_CLK |
|
10 |
GPIO12 |
MTDI, I2SI_DATA, MISO |
|
11 |
GPIO13 |
MTCK, I2SI_BCK, MOSI |
|
12 |
GPIO15 |
MTDO, I2SO_BCK, SP_CS |
At boot: must be low to enter flash or normal boot (high enters special boot modes) |
13 |
GPIO2 |
I2SO_WS, U1TXD, U0TXD |
At boot: must be high to enter flash or normal boot (low enters special boot modes); Typically is used as uart1 TX for debug logging |
14 |
GPIO0 |
SPICS2, CLK_OUT |
At boot: low causes bootloader to enter flash upload mode; high causes normal boot |
